14112351 TOY DUMP can AND COUPLING.

To all whom it may concern:

Be it known that I, MILTQNS. DUNKEL- BERGER, a citizen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Toy Dump Cars and Couplings, of which the following is a specification.

This invention relates to new and useful improvements in toy dump cars and conplings, and has particular reference to a toy car whose body may be tipped by pulling upon a chain, cable or like means.

It is the principal object of my invention to provide a toy dump car having a tiltable body portion with balancing and locking means for normally holding it in a horizontal position to receive'a load.

It is another object of my invention to provide meanssuch as a chain that may be pulled from a distance to disengage the locking means from the body to permit the latter to be automatically tipped for the purpose of discharging its load.

It is still another object of my invention to provide simple, eflicient and readily operated means for coupling the dump'car to another toy car or engine.

Other important and incidental objects will be brought out in the following specification and particularly set forth in the subjoined claims.

In the accompanying drawings illustrating one form of embodiment of my invention, Figure 1is a side elevational view of my toy dump car showing the tiltable body in a horizontal load-receiving position; said view also showing aside elevation of the rear end of another car to which the first car is coupled by my improved cou pling means. Figure Qis a front view of my improved dumpicar. showing its tiltable body locked in a horizontal position. Figure 3 is a side elevational view of my toy dump car showing the tiltable body in a vertical dumping position, said'view also showing the second car uncoupled from the Figure 4 is a top plan view of the locking device. Figure 5 is a side elevational' view of the female coupling-member. And Figure 6 is a side elevational View of the different parts of the male coupling member.

Referring to the accompanying drawings for a detailed description of the form of embodiment of my invention illustrated therein, the numeral 1 designates a toy car frame which preferably comprises a light, durable casting which is supported by wheels 2, 2. Projecting upwardly from the front and rear portions of the casting 1 are integral supporting standards 3, 3. Secured to support, with theupper end of the arm 6, a dump or tiltable body 8 which is suit-- ably formed from sheet metal in tray shape to receive grain, sand or a like substance.

For the purpose of normally maintaining the body 8 in a horizontal position, there is suitably secured to the lower end of the lever arm 6 a balancing weight 9. (See Figure 1'.) In order to lock the body in this position, the following means are provided. Referring to Figures 1, 2 and 3, there is hingedly secured to a shaft 10 supported in the front portion of the frame 1, a bell-crank lever 11. At its upper end this lever has an inwardly-extending yoke por tion 12 which is adapted to straddle the front standard 3 and the lower end of the lever arm 6 to lock the latter in a vertical position, thereby to' maintain the body 8 in a horizontal position for the purpose of receiving and holding a load. (See Figures 1 and 4.)

Secured to the upper end of the bell-crank lever 11 is an aperturedear 13 which re ceives one end of a chain 14. When a pull is exerted upon this chain it will draw the yoke portion 12 of the lever 11 free from the lever arm 6 as shown in Figure 3, to permit the weight of the load in the body 8 to tip it to a vertical position as shown in said figure, for the purpose of discharg ing its load. At its lower end the bellcrank lever 11 terminates in an inwardlyprojecting tongue part 15 which is adapted to engage t e arched portion ofthe from;

standard 3 when the upper porti n of the 'see'n' that'by pulling upon the chain 14:, a

child can wi thdra-w the yoke end of the bell-crank lever free from the lever arm 6, whereupon the body 8 will automatically dump its load and'thereafter automatically return to its horizontal position. If de sired, the upper end of the chain 1 1 may be attached to a hook 16 secured to the dump body 8 as'shown in Figure 2, when the car is not'to be dumped.

. For the purpose ofeoupling the dump car just described to'an'other car 17 the following means are provided. Projecting outwardly from each end of th'ecasting 1 is a female coupling member '18 which has a top concave portion 19. Secured to the rear'end of the car 17 is an outwardly-projecting 'memb'er 20 to which there is pivotally attached by a'pin' 21, a hook piece 22 having an'inwardly curved nose portion 23 at its lower end for engagement in the concave portion 19 of I the female coupling member 18'; Hingedly securedby' a pin 24 to the member 20 behind the hook piece22 is a looking or stop member 25. At its rear end thismember has an extension 26 which is adapted to limit the forward-movement of the upper end of thehook piece 22. Therefore, when the nose portion 23 of the hook piece '22 is within the concave portion 19 of the coupling member 18, and the stop member 25 is'in a horizontal position as shown in Figure's l and 6, said hook piece willbe maintained in connection with said coupling member by the engagement of the rear 'straightend of the hook piece with the extension 26 of the stop member. u i

For the'purpose of elevating therear end of the stop member 25 so that the upper end o'f'the hook piece22 may'move a sufiicient distance to permit its nose portion 23 to clear the end. of the coupling member 18, the following means are provided. Referring toFigure 6 there is fixedly secured to a shaft (See Fig 2'? supported in the rear end of thecar 17,

anarm28. When the shaft is turnedby a crank 29"fa st on its outer'end, the arm 28 will engage boss 30 on the front reduced end of the stop member 25 to elevate its rear extension 26." Now, whenthecarl? moves forwardly,flthe'curved nose portion 23 of the'h'ook pieceis free'to slide out of the recessed portion 19 of the coupling member 18, s nce the r'earwardmovement of the upper end of the hook piece -will ntit be opposed when the extension 26 on the stopmember 25 is raised above it as shown in Figure 3. Furthermore, when the extension 26 of said stop member is inan elevated position, the cars are free to be coupled, since the curved noseportion 23 of the hook piece will readily slide over the end of the coupling member 18 to'enter its recessed portion 19 when it is forced against said end of the coupling member. The nose portion of the hook piece may then be firmly held in the recessed portion of the coupling member 18 by returning the stop piece 25 to its horizontal position through the instrumentality of the crank 29 or other means. It is thus seen that I have provided simple and easily operated means for coupling two cars together.

For the purpose of dumping one car when the other car is'pulled away from it, I have provided on the rearend of the car 17 an upwardly projecting member 31 to which there is secured a hook 32 to receive the free end of thechain 1 1. Accordingly when the dump car is uncoupled from the car 17 and,

the latter is drawn forwardly, it will exert a sufficient pull upon'the chain 1 1 to'cause the latter to draw the yoke portion 12 of'the bell-crank lever 11 on the dump car, free from the lever arm6, whereupon'the'body 8 of the dump car will be permitted to tilt for the purpose of discharging'its load, as before described.

I do not wishto be'limitedto the details of construction and arrangement herein 1. A toy dump car comprising a frame and supporting wheels therefor, supporting members projecting upwardly from the front and rear ends of the frame, a shaft supported by said members, arms mounted on said shaft and projecting above it, a dump body supportedfby said arms, and pivotal locking means carried'by said frame to grip one of said armstohold the dump body in a horizontal position, and free to be pulled from said arm topermit said body to tilt to an inclined position.

21 A toy dump car comprising'a frame and supporting wheels therefor, supporting members projecting upwardly from the front and rear ends of said frame, ashaft supported by said members, arms mounted on said shaft and projecting above it, one of said arms having a balancing portion projecting below said shaft. a dump body supported by the upper ends of said arms, and pivotal locking meansjcarriedby said frame to grip the downwardly projecting balancing arm, and free tobe pulled outwardly from said arm to permit said body to "tilt to an inclined position.

3. A toy dump car comprising a frame on said lever, adapted to grip the weighted arm to hold the dump body in a horizontal position, and means for pulling said lever outwardly to disengage its yoke portion 16 from said weighted arm to permit said body to tilt to an inclined position.

In testimony whereof I have hereunto set my hand this 13th day of March, 1923.
